Hello, everybody!
My guest has two graphics card when it is running, one is GTX960, and other is video card that is created by qemu.
But my guest use video card default, and my screen is not light. I try checkout graphics card with vnc or spice, But it is suspend.
Could you help me? And may i checkout card in my host system with command? Because my connection with vnc or spice is not stable.
This is my vga card message:
